Ball Clay - Digitalfire

Ball clay is not a clay mineral in itself but contains other minerals primarily kaolinite but also montmorillonite halloysite and illite. Mica and quartz are also present in substantial amounts e.g. 10-20 for Tennessee ball clays. Ball clays are very plastic and much finer-grained than kaolins. They are easily slaked in water when dry.
